Waning Gibbous in Libra

Waning Gibbous on . The illuminated surface of the moon is 81% and getting smaller. The lunar cycle is 19 days old.

Moonrise and moonset

The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon phase and lunation details

Moon is entering ♎ Libra

Moon is passing first ∠3° of ♎ Libra tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 26 January 2051 at 21:20.

Wolf Moon before 4 days

Next Full Moon is the Snow Moon of February 2051 after 25 days on 25 February 2051 at 14:53.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1947".

Lunation 631 / 1584

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 631 of Meeus index or 1584 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 43 minutes and it is 1 hour and 32 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 1 minute shorter than the mean synodic month length. It is 5 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠313.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠313.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠334.7°.

Moon at apogee

Moon is at apogee at 19:46 about 16 days since last perigee on 15 January 2051 at 18:23 in ♒ Aquarius the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 12 February 2051 at 18:54 in ♓ Pisces.

Distance to Moon 405 173 km

This apogee Moon is 405 173 km (251 763 mi) away from Earth. It is 235 km further than the mean apogee distance, but it is still 1 536 km closer than the farthest apogee of 21st century.

Moon before ascending node

11 days after descending node on 20 January 2051 at 03:36 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 February 2051 at 07:49 in ♏ Scorpio.

Moon before southern standstill

8 days since the last northern standstill on 23 January 2051 at 08:46 in ♊ Gemini when the Moon has reached North declination of ∠19.697° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-19.572° at the point of next southern standstill on 6 February 2051 at 23:17 in ♐ Sagittarius.

Draconic month

24 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 10 days

In 10 days on 11 February 2051 at 06:41 in ♒ Aquarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
